TQ' JALL WHOM IT MAY CONCERN:

Be it known that we, JOHN W. CRAW, of NOIWZLlh', in the State ofConnecticut, and ABEL S. RANDOLPH, of Plainfield, in the State of NewJersey, have invented, made, and applied to use a certain: new anduseful improvement in Mosquito and Fly-Nets; and we do hereby declarethe following to be a. full, clear, and exact description of the saidinvention, reference being had to the annexed drawing, making part ofthis specification,

wherein- Figure 1 is an elevation of a window with our mosquito-netfitted thereto, the side slides being partially in section.

Figure 2 is a sectional plan of the same at the line a: x; and

Figure 3 is a separate elevation of one of the side bars receiving thenet.

lhe object-of our said invention is to-allow easy access to the blindsoutside the window, to allow the window to he opened or shut atpleasure, and the netting always to he in place for use, and notoin theway or liable to injury.

We make use of a roller, upon which the netting is wound by a spring, aheadhar,'to which the moving edge of the netting is attached, and slidesfixed to the edges of the window-casing, and receiving the ends of thehead-her; and said head-bar is fitted so as to be connected, removahly,to the bottom rail of the sash. By this construction the spring-rollerkeeps thenetting under tension, taking up the slack as the sash isclosed, the side slides keep the head-bar and edges of the netting inplace, and when the head-bar is disconnected from the sashthe window canbe opened without'spreading the netting, said netting remaining inposition, but in a small compass, sees not to be in the way.

In the drawing, a represents a window-frame of any desired character; I)and c are the'sashes, fitted to slide as usual; 2' k are our groovedside slides, attached to thestop-bead of the window-frame; e is theroller for the netting f; and is the head-bar, perforated with holes, soas to set over pins that are introduced in the lower rail of the sash.The ends of the' head-bar 9 pass within g ooves in the faces ofthoverticnl slides z'k, that are attached to the stop-heads or framesa,- but atthe lower part of said slides i k the rib on the side of thegroove is removed, as seen in fig. 3, so thatthe head-oar 9 can be drawnoff or put'upon'the pins 2 in the sash-rail b. The slide k'is madehollow, so as to receive a contractile India-rubber cord, 3, or otherspring, from which a cord, 4, passes to the spool 5; on the axis of therollere, so as to rotate said roller, and-wind up the netting as thesash 6 is closed. The act of opening said sash 6 draws up the head-barg, and spieads the netting; and the cord 4 is wound upon the spool 5 bythis movement, and the spring 3 distended. The edges of the netting,remaining in the groove of the slides Us, and under tension, aresufiiciently tight to keep out 'flies, mosquitoes, &c.

This netting can be applied to the top or bottom sash, or to a slidingdoor or sash, and allows access with facility to the blinds outside thewindow, and does not obstruct the light when the window is closed.

If desired, small ribs of whalebone or skirt-spring ma; be introducedhorizontally in the nettinz. at suitable distances apart, to keep theedges of the netting into the grooved bars 2' and k.

We'do not claim a spring-roller and a bar connected to. the sash andreceiving the moving end of the netting, as these have been used.

What we'claim, and desire to .secure by Letters-Patent, is--- The bar g,in combination with the slides tile and spring-roller a, when the endsof the bar g are formed to 'enter and slide in the slides i k, and saidslides i I: are partially removed at their lower ends to allow the bar gto be removed from the pins 2, for the purposes and as set forth.

In witness whereof I have hereunto set my signature this twenty-sixthday of April, A. D. 1867. JOHN W. ORAW,

ABEL S. RANDOLPH.
